Connecticut Property Tax Calculator
Connecticut carries one of the heaviest property tax burdens in the country, with effective rates that consistently rank near the national top. The structure is conventional — a local assessor values the property and locally adopted mill rates are applied — but the levies themselves run high because property tax funds so much of local government here. Estimates on this page come from regional medians; select your Connecticut area above to translate a home value into an expected bill.

How property tax works in Connecticut
- An assessor establishes the assessed value; the mill rate adopted where you live is applied to it.
- Connecticut's effective rates are consistently among the highest of any state, so the levy matters as much as the value.
- Exemptions for qualifying owners and an appeal path for disputed assessments both exist.
Methodology
Rates are aggregate-derived from the Census Bureau's ACS 2024 5-year American Community Survey (total real-estate taxes paid ÷ total home value, by county). This is a statistical estimate, not a bill lookup — actual property tax bills vary by city, school district, and special-district levies layered on top of the county rate, and by any homestead, senior, veteran, or other exemptions you qualify for. Connecticut ranks #3 of 51 (including DC) by statewide average effective rate, where #1 is the highest.

Frequently asked questions
How much property tax will I pay in Connecticut?
More than in most states, at a given home value — Connecticut's effective rates rank among the country's highest. The calculator above applies your area's median rate to the value you enter and returns annual and monthly figures.
Can I lower my Connecticut property tax bill?
Relief programs for seniors, veterans, and disabled homeowners exist in many communities, and every owner can appeal an assessment believed to be above true value. Given how high Connecticut rates run, a successful appeal is worth real money.
How is property tax calculated in Connecticut?
An assessor establishes your property's assessed value, and the mill rate adopted where you live is applied to it. Multiply the two and you have the bill — the calculator above does exactly that with median local data.
Are property taxes deductible?
Yes for itemizers, via the federal SALT deduction — though that deduction is capped, and Connecticut's high bills mean many households hit the ceiling. Verify the current cap with the IRS.
